Increased intracranial pressure headache, mainly given to lower the cranial pressure treatment, generally the intracranial pressure is reduced after the patient’s headache symptoms can be relieved. Clinically used antihypertensive drugs mainly include mannitol, glyceryl fructose and tachycardia. Specific usage includes 20% mannitol commonly used dose of 125-250 ml, every 4-6 hours, routinely given to intravenous rapid drip; tachycardia application of 10-20 mg, every 2-8 hours, into the pot; glycerol fructose is generally applied to 250-500 ml intravenous drip, 1-2 times a day. Increased intracranial pressure is mainly seen in patients with severe large cerebral infarction or patients with large amount of cerebral hemorrhage, often due to cerebral edema, cerebral edema often begins to appear on the second day after the onset of the patient, cerebral edema aggravated after the 4th-5th day, cerebral edema is reduced after the 7th day, and basically recovered in the 14th day. Severe cerebral edema can cause increased intracranial pressure and may even lead to death due to brain herniation. If the patient has cerebral edema and increased intracranial pressure, he should be given prompt treatment to lower the cranial pressure.
